KOMPAS.com – Meteorology Climatology and Geophysics Council (BMKG) predicts an increase in the intensity of the Seroja tropical cyclone on 7-8 April 2021.
According to BMKG estimates, Seroja cyclone will move southwest away from Indonesian territory.
Responding to these conditions, the National Disaster Management Agency (BNPB) has coordinated with the Regional Disaster Management Agency (BPBD) in six provinces.
The six provinces are:
- Central Java BPBD
- BPBD East Java
- BPBD Lampung
- BPBD Bali
- BPBD West Nusa Tenggara (NTB)
- BPBB East Nusa Tenggara (NTT)
- BPBD DI Yogyakarta
Head of the BNPB Disaster Data, Information and Communication Center, Raditya Jati, said the Seroja tropical cyclone would contribute significantly to increasing atmospheric lability and the growth of rain clouds in parts of Indonesia.
“In addition, it can encourage an increase in wind speed which has an impact on increasing wave height in parts of Indonesian waters,” said Raditya, quoted from BNPB press release, Wednesday (7/4/2021).
Raditya said BNPB had submitted a number of recommendations to the six provincial BPBDs to deal with the tropical cyclone Seroja.
First, conduct regular coordination with related agencies and district and city administrative territories in the local areas under the six provinces.
Second, monitoring to get the development of weather early warning information and potential disaster threats through several sites managed by BNPB, BMKG and Lapan.
Third, increase socialization, education and mitigation activities related to prevention efforts flood and flash floods using electronic media or social media considering that Indonesia is experiencing the Covid-19 pandemic.
Prepare an evacuation site
Fourth, coordinate with related agencies and institutions (Dinas Kominfo, RAPI, Orari, Senkom, Regional DRR Forum, and other related parties) in disseminating information on early warning of floods, flash floods and landslides periodically to the community, in particular. who live in a high risk area.
Fifth, prepare and disseminate separate evacuation sites between healthy communities and confirmed positive Covid-19.
Sixth, coordinating with local health offices regarding the preparation of health facilities, such as hospitals, health centers and referral systems, especially for hospitals located in high-risk disaster areas.
Seventh, preparing 3T infrastructure (tracing, testing, treatment) in evacuation and evacuation sites and enforcing health protocols (3M) during evacuation sites.
Eighth, identifying the needs and availability of existing resources in the area (human resources, equipment, logistics, etc.) and planning their mobilization for refugees.
Ninth, if necessary, can determine the status of a disaster emergency and the establishment of a command post for handling disaster emergencies as well as activating the contingency plan into an operational plan.
Finally, coordinating disaster emergency management can contact the BNPB Operations Control Center (Pusdalops). This aims to support early handling before an incident occurs.
Potential for rain and waves in some areas
Raditya added, based on monitoring of Seroja’s potential impacts, BMKG estimates that there is potential for rain with moderate to heavy intensity accompanied by lightning and strong winds in a number of areas, namely:
- Central Java,
- D.I. Yogyakarta,
- East Java,
In addition, there is a potential for wave height of 2.5-4.0 meters which is likely to occur in the western waters of Lampung, the western Indian Ocean of Lampung, the southern Sunda Strait, the southern waters of Java Island to NTB, the southern Indian Ocean from Java Island to Bali, the southern waters of Sumba Island to the island. Rote.
“Then the potential for wave height of 4.0-6.0 meters is predicted to occur in the waters south of NTB to the south of Sumba Island,” said Raditya.
